Speaking about her twin brother and her father's fundraising challenge, Megan Mackay said: ‘Ruairidh was fulfilled with joy, excitement and pride, and couldn't wait to start his career in the Royal Navy. Unfortunately, this opportunity was snatched away and his future taken from him.

‘This charity (RNRMC) has helped my family immensely during a tragic and heartbreaking period, and we want to give something back.

‘You helped us during the worst time of our lives, and for that, I thank you from the bottom of my heart.’
